TABLEWARE WASHER.

Application filed October 13, 1926. Serial No. 141,398.

The invention relates toimprovements in dish or tableware washingapparatus and particularly to a type in which the cleansing is effectedby subjecting the ware to a spray of cleansing orrinsing fluid underpressure. An object of the invention is to provide a traveling sprayerconveyed in a cycle about a net form of tray or holder in which the wareis placed or stacked to spray or shower the ware with either a cleansingor rinsing fluid delivered under pressure progressively.-

in downward, upward and lateral varying angular directions to enable allsides or surfaces of the ware to be reached without agili5 tating ormoving the ware. v

Another object is to provide a dish or table ware washer as a po rtablecabinet with a washer compartment and a plurality of dif: ferent fluidsupply reservoirs beneath the compartment, the compartment andreservoirs being under drainage connection for conveying the fluid backto the reservoirfrom which the supply was taken, and a motor driven pumpadapted to be'thrown' in c0nnection with a selected reservoir fordelivering the fluid therefrom under pressure to a traveling sprayer inthe washer compartment,

the fluid from the reservoirs to the pump and the drainage from thewasher to the reservoirs being under a single control for alternatelyutilizing the fluid from the reservoirs independently. I

Further objects and features of the invention relate to details ofconstruction of the mechanism for simultaneously controlling a fluidsupply from several reservoirs to a pump and a drainage connection backto the reser'- .voir adapting the supply to be taken alterna'tely fromthereservoirs by the manipulation of a single control lever.

The apparatus herein disclosed is primanly as a portable dish washer,particularly for domestic service, and therefore, as a unit includes aplurality of liquid holding reservolrs, one for a-washing or detergentfluid, and a secondfor a. rinsing fluid, which traveling sprayer withinthe washer compartment, and from which it drains back into thereservoir, provision beingmade for alternately controlling the dischargefrom the reservoirs or drain thereto.

Referringlto the drawings, 1 indicates a portable cabinet preferablyconstructed of sheet metal and interior-1y subdivided to pro.- vide awasher compartment 2, reservoirs 3, 4',

beneath the washer compartment, and a 5 pump compartment 5. The washercompartment upon its opposite end walls. and toward. the base thereof isprovided with ledges 66. of angle iron construction for supporting amoved from the washer compartment through an opening in the front wallof the cabinet which is provided with a door 8 swinging downwardly asillustrated in dot and dash line, Figure 2. The ledges 66 as shown inFigure 4, rearwardly' are spaced from the end walls to provide a passageor clearance for the traveling sprayer pipe 9 conveyed in a rectangularcourse or path com.-

pletely about the dish-holding tra 7 by an 160.

endless carrier or sprocket chain 10. The sprayer pipe extendshorizontally with its sprayer nozzle-.11 at the forward end of the pipe9 disposed approximately medially of 7 the tray. The dishes andchinaware arestacked and positioned withinthe tray so that theirsurfaces can be reached from all sides from the sprayer nozzle in itstravel about the tray. 1 The dishes thus remain stationary duringthe-washing operatlon'so that there is no cause for them to becomebroken glass ware, are placed in an upset position of chipped.

The spraying nozzle is of a form to give a wide spread to the fluid andas it asses about the tray is always directing the uid against thedishesin various lines and angles downwardly and upwardly, so that a completewashing and rinsing is obtained ina considerable less time than would'bepossible in moving or agitating the dishes in the fluid. The dishes arepreferablystacked or set at an angle whilethe cups, deeper vessels,'or

so that the fluid will be drained therefrom onto the inclined base 12 ofthe washer com partment. The nozzle travels at an-appropriate rateand'the fluid is projected at a high velocity,- subjecting the ware inthe tray to a heavy shower of fluid which completely cleanses the same.The fluid after striking the ware drains therefrom upon the base of thewasher compartment and into the proper reservoir 3 or 4. Thesprocket'chain or endless carrier 10 is engaged upon the sprocket wheelidlers 13, four in number being provided so that the chain will move ina rectangular path and each sprocket wheel is respectivelyjournalled'upon'a stud 14 fixed to the rear wall of the cabinet orwasher compartment. The chain is transmitted by a sprocket wheel 15connecting with a'sprocket chain '16 leading into the motor compartmentand connecting about a sprocket wheel 17 upon the drivin shaft of thepump 19. This pump sha, is driven by a rocket wheel 20 connecting with achain 21 which in turn shaft 23 of an electric motor 24 on aplatform 25supported in the motor compartment 5.

The sprayer pipe 9 is suitabl secured to the sprocket chainand connectst rough flexible 'tubing 26 and universal coupling,-

stationary suppl pipe 27 g V The supply pipe 27 extends through the base12 of the washer compartment into the pump compartment and is rigidlyfixed thereto by'the lock washers 2828 disposed at opposite sides of thebase. The portion of-the supply pipe within the pump compartment has anL extension 29 connecting with the pump 19 and a drain valve '30 at itslower end. A pair of pivotally connected li'nks 31, 32, are respectivelypivotally connected. to the upper end of thesupply pipe 27 and thesprayer pipe 9 and serves to sustain the sprayer pipe in a horizontalplane, the links moving with the sprocket chain about the universalcoupling connecting "the tube 26 with the supply pipe 27. The tube 26and sprocket chain 10 are interposed between the rear' cabinet wall andpartition plate 33 in the washer compartment, the partition plate beingfixed to the ledges 66.' i

The fluid reservoirs 3, 4, connect with the pump, each through a pluralway valve 34 controlled by a hand lever 35. Reservoir 3 connecting withthe valve through a pipe flfid after it has been sprayed over thedishes, drains through a spout 39 into either of the reservoirs 3, 4,depending upon its setting, the spout being swivelledupon anipple 40engaged through and fixed to the base 12. The spout 39 is actuated inconjunction with the valve handle 35 by means of a link 41 connectingthe spout with a crank lever 42 swivelled in the bearing 43 of the wallof the reservoir 4, and the crank lever 42has a second arm 42 whichconnectswith' a link or fork 44 pivoted at 44 to the front wall of thecasing. The fork end of the connecting link 44 en gages an eccentric 45fixed upon the valve stem of the plural way valve 34. Thus, with theshifting of the valve, the-spoutis appropriately swivelled for draininginto thetankfrom the washer compartment through the spout. Thesestrainers are arranged to be 95 removable, access to them being hadthrough the opening 48 in the'base 12, the base beingflanged upwardlyabout the opening for receivmg the cover 49.

In the operation of the washer after the I tray 7 containing the dishesor ware has been placed in the washer compartment 2, the valve handle 35is thrown in an appropriate direction for conne cting the pumpwitheither reservoir 3 or 4 which contains the cleansing v fluid. Thisaction simultaneously moves the spout 39 so as to drain the fluid fromthe washing compartment into the reservoir from which'the fluid istakenby the pump. Upon starting the pump the cleansing fluid from thereservoir 3 is delivered to the sprayer nozzle 11 from which itdischarges in a spray upon the dishes. The carrier orsprocket chainlOcarrying the nozzle 11, being in transmission connection with the pump,is, thus, thrown into operation simultaneously withthe pump for movingthe nozzle at an appropriate rate about the tray or dishes. The sprayernozzle in traveling about the tray'directs the ray .first'in'onedirection, say downwardly om v 've the tray, against the dishes orarticles the tray and then follows in an o posite di- 'rection upwardlyfrom beneath t e tray so Y that practically all surfaces of the dishesare reached, it being recognized that the dishes are suitably, stackedin the tray so that aco'nsiderable area oi each dish can be reached bythe sprayer. The placing of the dishes, of course, is under thediscretion'of the operator so as to produce the most eflicient resultfor the kind and condition of warewashed, and likewise, the period forwhich the different sprays are run. After the ware has been subjectedfor the necessary period to the spray of the cleansing fluid, the handleis thrown to a reverse position which cuts oil the cleansing fluidsupply to the pump and puts in the rinsing fluid with the sprayercontinuing in its travel. The control of the handle 35 likewise controlsthe spout 39 so that in shifting from the cleansing fluid supply to therinsing fluid.

supply the spout is thrownlfrom said reservoir 3 to reservoir 4 so thatthe rinsing water is recovered or drained back into the reservoir forreplenishing the supply to the pump. If necessary, a second cleansingoperation and rinsing operation can be had, that is, the change from onefluid to another can be made at any time preferred by the operator.

Having described my invention, I claim: 1. In a dish washing machine, acasing, a dish-holding tray removably supported with- .in said casing, afluid sprayer traveling in a rectangular path about said dish-holdingtray, and an endless carrier within said casing for conveying saidsprayer about the tray.
